It's not good, check differential level.
If leak is slow you could get by with annual differential top off.
If your differential runs low you'll end up needing to replace it.

One of them there S cars
What are you talking about? He probably didn't use Genuine Mercedes Magical Differential Fluid that meets Mercedes spec UN1C0RN UR1N3 333.261, and it's obvious the magic built into the original fluid is wearing off!!!
But seriously, OP. VII is correct. Check differential fluid level and address it as necessary. On the bright side, those leaks are going to eventually stop when most of the oil runs out of the pumpkin. At that time, expect serious damage to start occurring. The trick is to repair or stay on top of the oil level. Keep in mind, the leaks can (and probably) will get larger.

Ahh in that case I would say you'll need to replace when it starts making noise.
You could regrease from time to time but that is an annoying job.

Best to put in a new axle when the time comes. Wear on the CVs on both ends and possible infilration of dirt and water where the grease has started to leak out.
Labor to do the whole axle is no more, possibly less, than replacing a boot and repacking an old CV joint
